A homeowner in West Milford, NJ, was experiencing sagging floors above the crawl space and immediately wanted to fix the issue. Quality 1st Basements arrived to the job site and installed 8 SmartJacks along with a full crawl space encapsulation system. The SmartJacks are designed to stop the foundation from settling and can raise your sagging floor back to the proper level. We also installed our CleanSpace Vapor Barrier System! The Clean space liner is used to protect the crawl space from water, mold, cold air and creepy crawlers.
